SICK WTT12L-A2523 PowerProx Laser Distance Sensor (1082477)

WTT12L-A2523 – The SICK WTT12L-A2523 is a compact photoelectric laser distance sensor using background suppression and optical time-of-flight (ToF) for accurate mid-range detection. With a 100 mm to 1,400 mm sensing range, it provides consistent measurement in demanding industrial automation tasks.

Its visible Class 1 red laser, 12-bit analog resolution, and push-pull digital output (PNP/NPN selectable) make it an ideal option for precision tasks, particularly where repeatability and robustness are critical.
